Adding this CSS to an element:
does not work as expected. Cursor actually shows up as a sw-resize cursor. the nwse-resize cursor is unaffected, and shows up as expected.
Tested this in Safari 5.1 (MacOS 10.7) and nesw-resize works as expected. This bug only shows up in the latest webkit nightly.
This is due to a typo in WebKitSystemInterface changes for <http://trac.webkit.org/changeset/90087>.
Safari 5.1.1 on Lion is affected.
I could have sworn I tested those all!
Fixed in <http://trac.webkit.org/r97490>.
